"There must be no problem here. Catherine sat on the ground with a strong look, took out a water bottle and poured half of the pot hard, wiped the sweat from her forehead and said, "Can the defense system you set up completely block the enemy's attack?"

"Unless there is another demigod, even if they are allowed to attack unscrupulously, this fortress alone will be able to hard-reach for thirty minutes. Freya said confidently, "With Vivien's magic circle shield, they don't want to break through here in an hour." ”

"That's good. Catherine breathed a sigh of relief, but after a casual glance around the fortress, her eyes were already red, and her face was pale and she stared at the ground. On the ground, more than 20 blank 5,000 terr spars were thrown messily, Catherine jumped on the spot, her fingers were trembling, pointed at the spars on the ground and screamed, and asked in a desperate and expectant voice: "These spars must have been blank originally, haha, haha, it must not have been used by you just now, definitely not, hahahaha." ”

"Accept it, big sister. Lina patted Catherine on the shoulder with pity, sighed and pointed to the twenty crystal guns floating around her, and said, "I watched Freya charge these crystal guns piece by piece, and you are doomed to be disappointed. ”

"Oh no. Catherine covered her head and groaned, "Freyya, how have I forgotten your habit of using a hedrome as easily as Pannis, God, have mercy on me." ”

"Hehe, eldest sister, so you can't stand it?" Freya didn't mean to reflect at all, but gloated and pointed at Vivian and said, "Go and see Vivian, I hope you don't collapse." ”

Catherine turned her head cautiously, her eyes were almost closed, only a slit was opened, she quickly glanced in front of Vivien, and said with a long sigh, "It's okay, it's just three blank spars." Wait, didn't I just come in without a single piece? Why did it suddenly become three?"

Vivien sat cross-legged in the center of the circle, holding her chin and not knowing what she was thinking, she mechanically threw down a blank spar in her hand, and took out another five-thousand-terre spar from the pocket in front of her and held it in her hand, and said in a very sluggish voice: "Why? Of course, it's because I used it." I extracted the crystal energy from the hedron, and it naturally became blank. ”

"Hey, wait a while and then come out of your mind, you're consuming too fast. Catherine broke down and said, "What the hell are you doing to consume this amount of hedrons?"

"Charge the circle. Vivien finally came back to her senses and asked puzzledly, "Sister, you don't think that a magic circle of this strength can be supported by my own magic alone." ”

"Not really, but you're a drain. Catherine said bitterly, "I've only been in for three minutes, and you've already consumed four pieces, do you have to consume one piece every minute?"

"It's not that exaggerated. Vivien shook her head and said, "It's just that when the circle is first activated, you need to fill up the energy, and another piece is almost enough, and the rest can be replenished as you consume." According to my estimates, it will cost about ten dollars. ”

"Ten hedrons, you're pretty good compared to Freya's. Catherine felt like she was going crazy, and she felt relieved to hear that she would consume ten thousand gold worth of hedrons. However, this sense of reassurance disappeared immediately, as Vivien casually added, "Well, every time." ”

"Wait?" Catherine stiffened and asked in a dry voice, "What do you mean every time?"

"It's like this every time you try to fight. Vivien replied as a matter of course, "If you want to move, you have to re-erect it, and you probably need so many hedrons every time you re-erect it." Well, maybe use one or two pieces less, depending on the strength of their attacks. ”

"I'd better go out and continue using the Legion Technique. Catherine stood silently for a moment, then took her shield and knight's sword and said, "If you stay here, I think I'll die of a broken heart." ”

"There is a pay, there is a gain. Freya said elegantly in an almost aria tone: "Master Simon once said, with sweat and labor, we harvest food, pay for learning, we harvest knowledge, pay blood and life, we reap glory, human beings, you are always in the process of giving and reaping...... Wait, big sister, calm down, okay I'll shut up. ”

Catherine retracted her murderous gaze, sighed, threw down her weapon again, and said weakly: "Anyway, if you consume so much, you have to step up the search, and you can't rest for too long." Lina, you can go out with me to search together, let's act together, the search for two people may be faster, but you pay attention to safety, don't get too seriously injured. ”

"I've thought so for a long time. Lina took off the hammer, took out a cloth and wiped it and said: "There are two people inside and outside, and you can support each other if you encounter any problems, and I really don't feel at ease to let you go out alone, eldest sister." ”

"Boom. There was another violent crash and an explosion of magic, but the fortress was still as strong as ever, showing no signs of shaking. Catherine didn't really rush out, but sat down and continued to regain her strength, and asked with some surprise: "Why is there still a magical voice, how did you build these two defenses?"

"The outer layer is my shield, of course. Speaking of magic-related topics, Vivien immediately became energetic and explained seriously: "Do you remember the elemental barrier that surrounds our Yarra world? Of course, my shield has nothing to do with it, but it is a bit of a creative imitation. My elemental barrier is also filled with free elemental energy, compressing it into an invisible film of light. This light film is not defensive, and anything can actually pass through, but except for energy and long-range attacks, the rest of the things, including people and weapons, if you want to pass through, the light film will automatically launch a magic counterattack, which is equivalent to taking my high-powered single attack magic once a second. The weakness of this tactic lies in the circle, unless they destroy the circle, it is impossible to attack the light film without substance, so they can only let the spell bombard until the circle's energy is exhausted, which is why I have to keep charging the circle. ”

"And what if they find a way to destroy the circle?" Catherine asked, "Although they are under control, they still have a little basic judgment, and they should be able to think of the root cause of the destruction." ”

"That's when it's my turn to move the fortress. Freya said proudly, "My fortress just covers the circle, and if they want to destroy the circle, they must destroy my fortress first." But I'm a big believer in the strength of goblin metal, and it's not easy to destroy this fortress. ”

"I just wanted to ask. Catherine nodded and asked, "It's all made of goblin metal?"

"Most of the parts, including all the exterior and interior walls, are made of goblin metal, collected from the goblin ruins, and belong to the teacher's collection. Freya explains, "But because I put a lot of parts together, some of the key parts are forged from ordinary metal, but they are not the impact parts and are not exposed, so they are difficult to attack directly." ”

"That's amazing. Catherine exclaimed, "Then wouldn't the defense you two build together be unsolvable?"

"How could it be. Freya smiled wryly and shook her head: "If the other party also has a mechanic of the same level as me, let the other party attack, within three minutes the opponent's mechanic can discover the weakness of the fortress, and within five minutes the entire fortress can collapse." Of course, I can't stupidly watch him attack the fortress's weak points, so the rest is between the two mechanics. However, if there are any mechanics among them, I don't think they can maintain the observation and judgment of mechanics in a controlled state, which is the key to the battle between mechanics. ”

"Even if there is a weakness, this is already powerful. Catherine said, "But if the enemy targets the underground......"

"That's my job. Lina patted her chest, causing her chest to shake, "Under the light of my lord Denia, anyone who wants to attack from the ground or against the ground is very stupid. ”

"Then I'm relieved, it seems that it can be safely guaranteed here. Catherine thought for a moment, stood up and said, "It's almost time to rest, Lina, let's get ready to go out and start searching." ”

"It's been ready for a long time. Lina grabbed the mace and the letter to her feet, and the priest's robe was covered with her own leather armor, which was made of the leather of the Terracotta Hunter that Lina and Pennis had killed together. The rest of the leather was not made into another leather armor, but into a pair of arm guards and a pair of leggings plus a wide belt, on which Vivien personally inscribed several enhancement circles, when Lina used the augmentation technique to enhance her strength and physical strength, it could greatly extend the duration of the magic spell, although it seemed nothing special, but it was extremely practical for Lina. Before this departure, a few pieces of equipment had just been completed, and Lina was very excited to carry them with her, but she never had a chance to use them, this was the first time that several pieces of equipment were worn, but several other girls were hoping that they would never have a chance to play an effect, at least not a chance to play a defensive effect. Of course, Lina didn't know what the other girls were thinking, so she finally adjusted the new equipment very curiously, and then nodded to Catherine and said, "It's ready to go." ”

On the outer wall of Freya's mobile fortress, a door to the outside world has once again opened. The controlled sea tribes who had been attacking the fortress naturally did not let go, and rushed towards the door, and then were mercilessly blasted away by the magic attack brought by the elemental barrier. Taking advantage of this opportunity, Catherine and Lina rushed out one after the other, and the gate slowly closed behind the two of them, and the hedron spears that followed the fortress began to roar.
